Down in the mouth, depressed (8)
I believe the answer is:
downcast
I believe this clue is a double definition.
'down in the mouth' is the first definition.
(thesaurus)
'depressed' is the second definition.
(I know that depressed can be written as downcast)
(Other definitions for downcast that I've seen before include "Low in spirits" , "disheartened" , "Sad" , "Depressed - looking at the floor?" , "directed towards ground" .)
